and Timor, C. occidentalism with its larger bill, would be its 

 representative form in Lombock, Flores, and Sumbawa. 

 Specimens from all these localities were attributed by me 

 (Cat. B. xx. p. 120) to one and the same species, and I am 

 still in doubt whether they can be separated. Dr. Hartert 

 has already recognised that specimens from Pantar and Alor 

 have the bill less powerful than those from Lombock.

Dr. Hartert has separated subspecifically from the 

 Celebesian ( '. sulphurea the Djampean Cockatoo (of which 

 he had only two females) on account of the smaller bill, 

 '2 1 nun. from the end of cere to the tip in a straight line, 

 while the bills of females from Celebes measure 27 mm: 

 " Iris crimson-lake ; orbital skin Avhite ; bill greyish black ; 

 feet dark grey; claws black" [Doherty). 



The value of this form, even as a subspecies, has always 

 appeared to me very cmestionable, and it seems that even 

 Dr. Hartert's confidence in C. djampeana has been lately 

 shaken, he having found that in specimens from Tukangbesi, 

 south-east of Celebes, the males have large bills like those
